dkms make fails under sudo

[ampledata]

When building a dkms module with sudo, I get the following error: sudo: argv[2] mismatch

I can reproduce this error with two different dkms modules.

I cannot reproduce this error if login directly as root.

I'm not 100% sure this is a dkms issue.

Steps to Reproduce

git clone https://github.com/fastoe/RTL8811CU.git
cd RTL8811CU
sudo make

N.B.:

1. Alternative dkms module for testing: https://github.com/morrownr/8821cu-20210916
2. sudo su followed by make can be substituted for sudo make

Expected Result

The RTL8811CU dkms module should build.

Actual Result

Some variation of:

git clone https://github.com/fastoe/RTL8811CU.git
cd RTL8811CU
sudo make

Even though those modules support DKMS, you didn't use DKMS for compilation, which means this error isn't related to DKMS.

If you're curious about the reason behind this error, edit /etc/sudo.conf and enable debug logs.
